IMPROVEMENT IN PLOW-JOINTE'RS.

Specification forming part of' Letters Patent No. 147,629, dated February 17, 1874; application filed December 2, 1873.

llo all whom lt may concern:

Be it known that I, HORATIO G'ALE, of Albion, in the county of Calhoun and State of l\flichigan, have invented an Improvement in Attachments to Flows, of which the following is a specification;

The nature of this invention relates to improvements in 'ihe attachment of jointers to the standards of plows; and consists princiA pally in the construction and arrangement of the various part-s, so that the same are more readily adjusted vertically.

Figure l is a perspective view ot' my attachments in place on the plow. Fig. 2 is a sectional elevation ot' the standard where the jointer is attached.- Fig. 3 is a perspective y view of the end ofthe arm, by means oi' which the jointer is secured to the standard.

Like letters refer to like parts in each figure.

ln the accompanying drawings, A represents the standard-ot' the plow, to which the land-side and mold-board are attached, and by which they are secured to the beam B. The side of this standard is provided with ser rations a', which engage with similar serrations b on the adjacent end ot the curved arm (l, which is also provided with a bolt, d, which passes through the slot h4 in the standard, where it is secured by a proper nut. By these -means the arm can be raised or lowered, as may be necessary, carrying with it the jointer This arm 1s curved, as

proper position over the plow-point to readily cut the sward. E is a curved arm pivoted to the beam at k, as shown, with its other end provided with a slot, Z, through which a bolt, m, and suitable nut, secure said arm to the beam. This arm is provided with a wrist-pin, upon which the wheel F rotates, as shown.

The dept-h of the furrow will be governed by the wheel, which is adjustable vertically, as described, when the jointer may be correspondingly adjusted to cut the sward by the devices described. A

One great object in attaching the jointer to the standard by a curved arm instead oi' to the beam, is to prevent clogging up by stubble and weeds, which occurs by the use of a vertical standard or arm which holds the jointer from the beam.

lhat I claim as my invention, and. desire to secure by Letters Patent, is

l. In combination with a serrated standard, A, the curved arm C, carrying' the jointer D, substantially as and for the purposes set forth.

2. The combination, with a plow-standard, of the jointer D, having arm C, and vertically adjustable upon said standard, substantially as described.
